Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an electrostatic air cleaner that utilizes discharge.

Conventional technology Conventional air purifiers usually have a linear cathode a and a plate anode b arranged facing each other as shown in Figure 5, and the flow of air by ionic wind is shown by arrow c. It is unidirectional.

Problems to be Solved by the Invention With the arrangement of electrodes in conventional air purifiers, the air flow due to ion wind is unidirectional, so when installed near a wall, the suction side wall surface is easily contaminated by dirty air. Furthermore, since the lines of electric force occur almost linearly, it is difficult to generate lines of electric force over a wide range.

Means and Effects for Solving Problems According to the present invention, the flat anodes are arranged on a flat plate at target positions on both sides of the linear cathode, so that the air flow caused by the ionic wind is reduced. Air passes from the outside through the air inlet of the safety cover and passes through the cathode.
After the dust in the air is negatively charged, the flow is divided almost at right angles to the left and right anode plates and evenly on both sides, so the charged dust is attracted and captured by the anode plate by Coulomb force, and clean air is generated. It comes to be sent out from the discharge port, and a T-shaped air flow can be formed.

In addition, the arrangement of the cathode and anode forms an obtuse isosceles triangle when viewed in a cross section perpendicular to the axis of the linear cathode, so the range in which electric lines of force are generated is similar to that of the conventional arrangement. It has a relatively wide range and can efficiently charge dust in the air.

Embodiments Below, embodiments of the present invention will be described based on the drawings.

In FIG. 1, plate-shaped anodes 2, which serve as positive DC high-voltage poles, are arranged parallel to the wire core of the cathode on both left and right sides, sandwiching a linear cathode 1, which serves as a negative DC high-voltage pole. It is installed almost flush and insulated above.

The cathode 1 is supported by a terminal 9 that is insulated and attached to a flat plate 8, and the mounting metal part is covered with a cover 11 and hermetically sealed.

On the other hand, in the cross-sectional view perpendicular to the wire core of the cathode 1 shown in FIG. It is covered so that the flow is divided toward the anode 2, and the air that has passed through the anode 2 is sent out from the discharge port 4 along the mounting surface 14 in parallel with the flat plate 8. 15 indicates lines of electric force.

FIG. 3 shows the external appearance of an embodiment of the present invention covered with the safety cover 13 and the air flow forming a T-shape.

Figure 4 shows the detailed structure of the cathode installation, in which the cathode 1 includes a tension spring 5, a mounting bracket 6, and a terminal conductor 10.
is connected to the high voltage power supply line 7 through the cover 11.
It has a structure in which it is attached to a flat plate 8 by a terminal 9 covered with a filling material 12 and molded with a filling material 12.

Effects of the Invention As explained above, in this invention, since the ionic wind blows from the cathode toward the left and right anodes, the air flowing from the suction port passes through the cathode and then bends toward the anode at an almost right angle. Since the clean air that has passed through the anode is discharged parallel to the mounting surface, dirty air does not flow along the wall surface and dirt can be prevented from adhering to the wall surface.

Further, by generating electric lines of force over a wide range, the dust charging effect is excellent.

Furthermore, it is easy to design a thin structure, increasing its value as an interior item.
